The Relationship between TDS and Water Quality
Definition of TDS TDS (Total Dissolved Solids) refers to the total amount of dissolved solids in water, including inorganic salts and organic matter. It is usually expressed in milligrams per liter (mg/L) or as electrical conductivity (EC). TDS measurement works by indirectly measuring water purity through electrical resistance. Pure water is an insulator, while natural water, rich in inorganic salts and organic matter, becomes a conductor. The greater the amount of these impurities in the water, the higher the conductivity. The Relationship between TDS and Water Quality TDS is an important parameter for evaluating water quality, but it cannot fully reflect the quality of the water. The following is a detailed analysis of the relationship between TDS and water quality: TDS Does Not Provide a Comprehensive Reflection of Water Quality TDS only reflects the total amount of dissolved solids in water and does not fully reflect water quality. For example, TDS does not reflect the presence of...
